Pelkey - Quebec > Northern Counties NY

Searching for ancestry of NELSON PELKEY (PELLETIER) and wife, JOSEPHINE HOULE. Believe both were born somewhere in Quebec, Canada, around 1850's. Lived at one time in Lyon Mountain, Clinton County, New York. At their deaths they were living near AuSable Forks, Clinton/Essex Counties, NY. Had a son born in Lyon Mountain christened Pelletier, so they used the Pelletier name in New York before changing it to Pelkey.

Any help is greatly appreciated. Would also like to hear from those who may be closely related to this family.
